Variable: WEEK_START_DAY

const WEEK_START_DAY: Record<CalendarSystem, number>

Defined in: date-math.ts:14

The day a week starts on, per calendar system, as a dayOfWeek() index (0 = Sunday, 6 = Saturday). Jalali weeks culturally start on Saturday; Gregorian ones on Sunday. This is the default for startOf()/endOf() (which take an explicit week start too, since Gregorian weeks also commonly start on Monday) and the week start buildCalendarGrid() lays rows out by.
